and this project adheres to [Semantic Versioning](http://semver.org/).
## [unreleased]
## [v0.5.2] 2024-06-16
## Fixed
- Replaced usage to `ptr::write_volatile` in UART module which is denied on more recent Rust
compilers.
## [v0.5.1]
### Changes
- Updated dependencies:
- `cortex-m-rtic` (dev-depencency) to 1.1.2
- `once_cell` to 1.12.0
- Other dependencies: Only revision has changed
## [v0.5.0]
### Added
- Reactored IRQ handling, so that `unmask` operations can be moved to HAL
- Added UART IRQ handler. Right now, can only perform reception, TX still needs to be done in
a blocking manner
- Added RTIC template and RTIC UART IRQ application
### Fixed
- Bugfix in UART code where RX and TX could not be enabled or disabled independently
## [v0.4.3]
- Various smaller fixes for READMEs, update of links in documentation
- Simplified CI for github, do not use `cross`
- New `blinky-pac` example
- Use HAL delay in `blinky` example
## [v0.4.2]
### Added
- `port_mux` function to set pin function select manually
### Changed
- Clear TX and RX FIFO in SPI transfer function
## [v0.4.1]
### Fixed
- Initial blockmode setting was not set in SPI constructor
## [v0.4.0]
